Abnormal discharge in early pregnancy

Im almost 5 weeks pregnant and very worried about misscarriage as Ive had previous misscarriages..in the last 24 hours Ive noticed that when I wipe..Im getting a small amount of stringy discharge which looks just like snot..its a dark greeny/slightly brown(but not resembling old blood) colour and it basically resembles something I would blow out of my nose..Im naturally very concerned..my gp took a vaginal swab yesterday but the results wont be back until monday and Im now feeling quite concerned..I dont have any pregnancy symptoms and Ive got a bit of abdominal pain..Im worried this is the start of a misscarriage

there was a post the other day with someone in the same position as you, turned out to be fine and loads of other people posted to say they had a similar thing. Sorry about previous mc, it does make you more jumpy. I had one last year and now im 16 weeks i had orange discharge, red, brown you name it! Oh and my symptoms came and went..ab pain is normal too, try not to worry and best of luck for the results from the swab

think the worry is the colour..but it doesnt seem to smell offensive..went to the gp and she said nothing can be done until results came back because it was more dangerous to prescribe medication that I didnt really need than to wait for the swab results..but then advised me that infections can cause miscarriage
